Polypeptides having alpha-hydroxy-gamma-carboxymuconic acid-epsilon-semialdehyde dehydrogenase activity

摘要

alpha-Hydroxy-gamma-carboxymuconic acid-epsilon-semialdehyde dehydrogenase, a gene encoding the enzyme, a recombinant vector containing the gene and a transformant carrying the gene, and processes for producing the enzyme and 2-pyrone-dicarboxylic acid by using the transformant.Use of the transformant can produce alpha-hydroxy-gamma-carboxymuconic acid-epsilon-semialdehyde dehydrogenase in a large amount, thereby permitting industrial production of 2-pyrone-4,6-dicarboxylic acid.
